Overtime Tax Savings in North Dakota
↻ Updated 2026 tax yearNorth Dakota is one of the states where the federal deduction reaches your state return too. Because North Dakota starts from federal taxable income and follows the Internal Revenue Code on a rolling basis, Schedule 1-A is already subtracted before North Dakota applies a graduated schedule from 0% to 2.5% — so the same $4,500 saves $580 federally and about $45 in North Dakota tax on top.
North Dakota starts from federal taxable income and conforms to the Internal Revenue Code on a rolling basis, so the deduction flows through to the North Dakota return automatically — no state legislation was required.
North Dakota starts from federal taxable income and conforms to the Internal Revenue Code on a rolling basis, so the deduction flows through to the North Dakota return automatically — no state legislation was required.
Because North Dakota conforms, the deduction cuts both bills — but $344 of Social Security and Medicare on the same dollars survives either way.
Why the deduction reaches your North Dakota return
The four OBBBA deductions are below the line: they reduce federal taxable income, and they leave federal adjusted gross income untouched. That is why most states never see them. North Dakota is an exception because its own calculation begins from federal taxable income rather than from AGI, and because it follows the Internal Revenue Code on a rolling basis rather than freezing to a fixed date.
Those two facts together mean no North Dakota legislation was needed. The figure North Dakota starts from already has Schedule 1-A subtracted from it, so the deduction arrived automatically the moment the federal provision took effect.
North Dakota then applies a graduated schedule from 0% to 2.5%. On the $4,500 in the example above, that is worth roughly $45 of state tax — a 1.01% effective rate on that slice of income.
What $4,500 of overtime premium is actually worth in North Dakota
Take a single filer with $62,400 of other wages and $4,500 of qualified overtime premium — the defaults loaded in the calculator above. Federal taxable income falls by the full $4,500, worth $580 at this filer's bracket.
North Dakota taxable income falls by the same $4,500, worth a further $45. Total saving: $625. The $344 of Social Security and Medicare on the same dollars is untouched, because these are income tax deductions and payroll tax is a separate system.
Move the sliders to your own numbers and the arithmetic follows. The two things that will not change are North Dakota's treatment — the deduction flows through and the payroll tax, which applies to the first dollar and the last.
What overtime tax relief does not do, in North Dakota or anywhere
Your overtime is still wages. It stays in boxes 1, 3 and 5 of your W-2 — the box 12 code TT is informational — so Social Security and Medicare are computed on exactly the same amount as before.
Only the premium half qualifies — the amount paid in excess of your regular rate, which is one third of a time-and-a-half payment. $13,500 of overtime pay produces a $4,500 deduction, not $13,500. The cap is $12,500 ($25,000 filing jointly) and it phases out above $150,000 of MAGI.
And all four OBBBA deductions expire after tax year 2028. Whatever North Dakota does between now and then, the federal provision has a fixed end date.
Frequently asked questions
Is overtime taxed in North Dakota?
Yes, but the federal deduction reduces it. North Dakota starts from federal taxable income with rolling conformity to the Internal Revenue Code, so your Schedule 1-A deduction is already subtracted before North Dakota applies a graduated schedule from 0% to 2.5%.
On the example above, that is worth about $45 of North Dakota tax on top of the $580 federal saving. $344 of Social Security and Medicare on the same dollars is unaffected.
How much will the overtime deduction save me in North Dakota?
About $625 on the example above: $580 federal plus roughly $45 of North Dakota tax, for a single filer with $62,400 of other wages and $4,500 of overtime premium.
A deduction is worth your marginal rate, not its face value, which is why $4,500 of income produces $580 rather than $4,500 of relief. Enter your own figures above for a number specific to you.
Does North Dakota conform to the federal OBBBA deductions?
North Dakota starts from federal taxable income and conforms to the Internal Revenue Code on a rolling basis, so the deduction flows through to the North Dakota return automatically — no state legislation was required.
That determination covers the overtime deduction; the senior and car loan interest deductions are tracked separately, though they usually follow the same rule because the mechanism is identical. Our conformity tracker shows all four deductions across all 50 states and DC.
Does the overtime deduction reduce my Social Security and Medicare tax in North Dakota?
No, and not in any state. Qualified overtime remain in boxes 3 and 5 of your W-2, so the 6.2% Social Security and 1.45% Medicare are computed on the same wages as before. On the example above that is $344 which no OBBBA provision touches.
Combined with North Dakota's income tax, which the deduction does reduce, that is why the practical relief is smaller than "no tax on overtime" implies.
